Since the central retinal artery and vein are the sole source of blood supply and drainage for the retina, such occlusion can lead to severe damage to the retina and blindness, due to ischemia (restriction in blood supply) and edema (swelling). [2] CRVO can cause ocular ischemic syndrome. Nonischemic CRVO is the milder form of the disease.
Central retinal artery occlusion: CRAO is characterized by painless, acute vision loss in one eye. [11] Central retinal vein occlusion: CRVO causes sudden, painless vision loss that can be mild to severe. [12] Branch retinal vein occlusion: sudden painless vision loss or visual field defect are the main symptom of BRVO. [13]
Hollenhorst plaques may cause retinal occlusion, where the plaque blocks blood flow through the retinal vessels, resulting in temporary or permanent vision loss in the affected eye. [1] However, while Hollenhorst plaques do become lodged in retinal arteries, they generally do not fully prevent blood flow so do not cause ischemia. [1]
The central retinal vein (retinal vein) is a vein that drains the retina of the eye.It travels backwards through the centre of the optic nerve accompanied by the central retinal artery before exiting the optic nerve together with the central retinal artery to drain into either the superior ophthalmic vein or the cavernous sinus.
Other conditions causing rubeosis iridis include central retinal vein occlusion, [2] ocular ischemic syndrome, [3] and chronic retinal detachment. Pathophysiology
Cherry red spot in a person with central retinal artery occlusion. Central retinal artery occlusion is characterized by painless, acute vision loss in one eye. [1] Upon fundoscopic exam, one would expect to find: cherry-red spot (90%) (a morphologic description in which the normally red background of the choroid is sharply outlined by the swollen opaque retina in the central retina), retinal ...
Vascular occlusion is a blockage of a blood vessel, usually with a clot. It differs from thrombosis in that it can be used to describe any form of blockage, not just one formed by a clot. When it occurs in a major vein , it can, in some cases, cause deep vein thrombosis .
A prior history of retinal vein occlusion was the only significant preoperative risk factor in a large retrospective series of 1659 consecutive cataract surgeries. [13] As one of the etiologic factors thought to contribute to macular edema is the release of prostaglandins. [11]
